A sample of 407 (224 males and 183 females with a median age of 29.4 years) part-time business students enrolled in evening programs at 3 colleges were surveyed to determine whether the attributes of successful middle managers correspond more strongly with the attributes of career women than with those of women in general. The students were randomly assigned to four target group conditions (women in general, men in general, career women, and successful middle managers). Each respondent completed one of four versions of the Person Description Index (PDI) to assess estimates of population rates for attributes occurring in the four target conditions. The prevalence of the traits within each target condition were averaged. The study confirmed that sex differences in stereotypes of career women do exist and create a double standard in evaluations of men and women in organizations. The female respondents viewed career women as primarily gaining masculine-positive traits but losing feminine traits that are both positive and negative. Although the male respondents tended to estimate higher prevalence rates on masculine-positive traits for career women compared with women in general, they did not perceive career women as different from women on any of the feminine-negative attributes.
